Built on solid ground, literally.

Whether it's a slab-on-grade for a shed, an ADU foundation, or footings for a home addition, we start with soil prep and compaction, place a vapor barrier under living-space slabs to control moisture intrusion, and reinforce with rebar or, on larger projects over expansive soil, post-tension cable systems.

Structural work is poured to a higher-strength mix than typical flatwork — usually 3000–4000+ PSI depending on the engineering requirements — and finished to the tolerances your framing or structure needs to sit level and square.

Parts of San Diego County sit on expansive clay soils that swell and shrink significantly with moisture changes — enough to crack a standard slab foundation if it's not designed for it. That's why post-tensioned slabs are common for new construction and additions in these areas, and why a soils report often drives the final foundation design rather than a one-size-fits-all approach.

For ADUs and additions specifically, we coordinate foundation design with your structural plans so the finished slab matches exactly what your framing package expects, avoiding costly field changes mid-project.

Keep grading and drainage sloping away from the foundation perimeter — water pooling against a foundation over years is one of the more common causes of later settlement or cracking issues, even on a well-built slab.

Watch for new cracking, doors or windows that start sticking, or visible gaps forming at foundation lines — these can be early signs of soil movement worth having evaluated before they become bigger structural concerns.

Need a plumbing, drain, or utility line routed through an existing slab? Our concrete cutting services page covers slab openings and trenching for approved layouts — note that post-tension slabs require scanning and evaluation before any cutting.
